Chinese Passanger Jets

How long does the demand for large passenger jets continue? Without straining too appreciably, one might consider China and its population and quip; "Faster than Charles Lindberg with a ransom letter." Indeed, this growing country is ordering Boeings and Airbuses in galactic proportions, but long enough for China itself to get in on the production? In this week's issue, the Economist is without a doubt.
A Chinese jet that is strictly Chinese might take 10-15 years before being available. Some essentials have not yet been developed, but foreign help has been solicited and China is already involved at some point in the production line of nearly every aircraft manufacturer under the sun. China is more than able and definitely willing. Pilots are already training, as we speak.
